Knowledge construction is widely concerned with the development and application of Constructivist Learning Theory. It’s a new learning metaphor of teaching for understanding mostly starting in the virtual learning community or a virtual forum. As a virtual learning community with function of polymerization, exchange, sharing, blogosphere can be used to support the construction of knowledge."Modern educational technology" course of China Central Normal University use the blog and blogsphere to promote students’ learning.

At the same time, the author use scheme of learning activities to conducted two rounds of action research. The author observed the effect and analysis the advantages, difficulties and problem solving method of the blogosphere learning platform in support of the learners in collaborative learning.This thesis is divided into five chapters, and the main contents of each chapter are as follows:The first chapter is mainly about the research background, the purpose and meaning of this research, and explains the research object and research methods.The second chapter is the literature review and theoretical basis. It defines the related concepts, analyzes the current situation both at home and abroad, and describes the relevant theoretical basis.In the third chapter, the author described the design process of knowledge construction learning activities in the blogsphere platform, and made a specific analysis. Then the author designed the scheme of learning activities used the action research.In the fourth chapter, the author did the two rounds of action with the scheme of learning activities designed in the last chapter. In the first round of action research, the author mainly observed the effect and the problem in the process of implementing scheme of learning activities, and Proposed solutions. In the second rounds of action research, the author improvement design of learning activities based on the first round of action research, and then observed the effect and made conclusion. The fifth chapter is the summary and Prospect of this thesis. It’s the summary of the two rounds of action research. Then the author presented the views about the limitations and the next study.
